EN-EL14 Rechargeable Li-ion Battery
I bought my D5100 with kit lens & purchased the AF-S NIKKOR 55-300mm DX VR lens also on 16 Mar 2012 and the last 2 times I've gone to charge my battery it's still "blinking/charging" after being plugged in for over 7 hours.
Am I doing something wrong or is it time to replace it and it's NOT EVEN A YEAR OLD YET?!?!???

I bought the d5100 and so far its been great. I have recently started doing night time, time lapses of the stars with about 400-500 photos of 10-15 second exposures, i was at first concerned since there are no battery pack options. But it turns out my d5100 usually has at least half of its battery left when finished. Great battery, highly recommended!

I think that the review by Eggroll, back in March, explains it all, and gets my applause.
When I got my D5100 and started using it, I was taken back by how quickly the battery ran down - on the first charge of the battery. I was concerned about the use of Live View, the 800 gram internal focus 28-300 lens, and video photography. So I bought a backup battery and read up on two-battery grips for the camera.
I use the camera during day long cruises (hikes) through the mountains.
But everything seems to be working fine after the second charge and as-necessary use of Live View. I shot 200 pix per day for several days with no change in the camera's battery level indicator.

Great battery life..
I have had the D3100 over a month now. Took several hundred photos in Thailand, Singapore and Phoenix AZ before returning home. Only had to charge it once. 3 week trip. I never used live view and only a few flash photos. After I returned I took about 50 shots at a B-Day party, indoor, all flash. Batter it still in it and shows about 25% left.
